Amateur here trying to learn RWD and I've got an issue with targeting iPad's which is baffling me. I perhaps foolishly tried to convert the old 960 static grid to responsive as I thought it would be a better learning exercise than using a fluid grid framework, but I think that's causing issues in itself.

Scaling the browser on a desktop seems to work, as does viewing the site on an iPhone but when viewing the site on the iPad, it seems to pick up styling from a kind of 'limbo' between the desktop and iPhone queries.
